Even if one commits the most abominable actions, if he is engaged in devotional service, he is to be considered saintly because he is properly situated.

Lord Krishna gives such a relief to persons who are the most fallen. He consoles that it is never too late. No matter how much fallen you are, how much abominable deeds you have committed, if you start devotion in a single minded fashion, i.e. ananya bhava, then you will be considered as a sadhu, a saintly person. Realize very clearly, that it is a statement spoken by none other than the Bhagvan Himself.
